Abstract: Methods and apparatuses are provided for channel access switching in a wireless communication system, with or without Listen-Before-Talk (LBT), and/or with different types of efficiently operated LBT. A device, including a User Equipment (UE) or a base station, can determine whether and/or how to perform LBT for a transmission based on a property of the transmission. The property could be a resource allocation for the transmission. The property could be a way to allocate resources for the transmission. The property could be a length or size of resource allocated for the transmission. The property could be an amount of resources allocated for the transmission. The resource allocation could be a time domain resource allocation and/or a frequency domain resource allocation.

Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE receives an indication from a base station, wherein the indication is indicative of monitoring a power saving signal in one or more monitoring occasions and at least one monitoring occasion of the one or more monitoring occasions is associated with a Discontinuous Reception (DRX) ON duration and is within Active Time associated with the UE. The UE does not monitor and/or skips monitoring the power saving signal in the at least one monitoring occasion. The UE monitors Physical Downlink Control Channel (PDCCH) during the DRX ON duration.

Abstract: A method and apparatus are disclosed, from the perspective of the UE, for reporting channel state information (CSI). In one embodiment, the method includes a UE being configured with at least two CSI-RS (Channel State Information-Reference Signal) resources. In addition, the method includes the UE performing measurements on the at least two CSI-RS resources. The method also includes the UE generating multiple CSIs according to measurements on the at least two CSI-RS resources, wherein at least one CSI corresponds to measurements on more than one CSI-RS resource. The method further includes the UE reporting at least one of the generated CSIs.

Abstract: Methods and apparatuses estimating pathloss of PUSCH in a wireless communication system are disclosed herein. In one method, the UE receives a first configuration of a first serving cell and a second serving cell, wherein the second serving cell is a pathloss reference for the first serving cell. The UE receives a second configuration of multiple downlink bandwidth parts of the second serving cell, wherein a downlink bandwidth part among the multiple downlink bandwidth parts is an active downlink bandwidth part. The UE estimates (or derives) a pathloss for an uplink transmission in an uplink bandwidth part of the first serving cell based on a reference signal in the downlink bandwidth part.

Abstract: A method and apparatus are disclosed. In an example, a User Equipment (UE) is configured with a size associated with downlink control information (DCI) corresponding to one or more preemption indications. In some examples, the size is equal to a first value that is not a multiple of a defined value. Alternatively and/or additionally, the UE is configured with a starting position of a field associated with the DCI. The starting position is equal to a second value that is a multiple of the defined value. Alternatively and/or additionally, a first DCI comprising a first preemption indication is transmitted to the UE based upon the size and/or the starting position.

Abstract: A method and apparatus are disclosed from the perspective of an User Equipment (UE). In one embodiment, the method includes the UE deriving a first pathloss value from a first pathloss reference of a serving cell, wherein the first pathloss value is used for deriving a power headroom value included in a first power headroom report. The method also includes the UE deriving a second pathloss value from a second pathloss reference of the serving cell after deriving the first pathloss value, wherein the second pathloss reference is used for power control for a first Physical Uplink Shared Channel (PUSCH) transmission on the serving cell. The method further includes the UE deriving the pathloss change based on the first pathloss value and the second pathloss value. In addition, the method includes the UE determining whether a second power headroom report is triggered based on whether the pathloss change is more than a threshold.
